Mr Witt's Widow by Antonio Hope

To fit square pegs into round holes is one of the favourite pastimes of Nature. She does it roughly, violently, and with wanton disregard of the feelings of the square pegs. When, in her relentless sport, she has at last driven the poor peg in and made it fit, by dint of knocking off and abrading all its corners, philosophers glorify her, calling the process evolution, and plain men wonder why she did not begin at the other end, and make the holes square to fit the pegs.

The square peg on which these trite reflections hang is poor Neaera Witt. Nature made her a careless, ease-loving, optimistic creature, only to drive her, of malice prepense, into an environment -- that is to say, in unscientific phrase, a hole -- where she had need of the equipment of a full-blooded conspirator.
